At all four tables the auction started 1♠ x ?
In the companion poll, virtually everyone bid 4♠, with a couple of votes for 3♠. I don't know if you are all simple honest citizens, or you don't admit to what you would actually do at the table, but when this board came up in a teams-of-eight competition these were the four auctions:
Table 1
---------
1♠ x 4♠ x
all pass
NS -500 (they only found one diamond ruff)
EW had agreed to play double as take-out 'to 4S' but didn't know if the double of 4S was penalties or not.
Table 2
---------
1♠ x 3♠ 4♥
all pass
NS -510
West should have bid over 4♥, I think, but East is known to be a very aggressive bidder and at least the pre-empt made life a little difficult for them.
Table 3
---------
1♠ x 2♦* 2♥
P 4♥ all pass
2♦ was a transfer to hearts.
NS -510
You could argue the psyche worked, but East/West were not a strong pair and it's probably that anything would have worked.
Table 4
-------------
1♠ x 2♥ 4♥
P 4♠ P 5♦
P 5♠ P 6♥ all pass
2♥ was 'natural and forcing'
NS -1010
Compared to tables 1 & 2, East had the space to show a real value-based 4H bid (rather than a stretched guess) - better than a minimum double or 3♥ bid. EW had plenty of room to bid confidently to a small slam while deciding they didn't have quite enough for a grand.
So here's the rant: psyches are fun. A well-placed psyche can play havoc with the opponents' bidding. But if you look at top class bridge you will see this type of baby psyche (where you invent a suit holding a pre-empt or a pre-emptive raise) is almost never seen. If you look at less than top class bridge it is very popular, because against bad players they work well.
So I really wish people would stop trying to have fun when they have a fit and just pre-empt to the limit instead. Taking up space always causes the opponents problems. Bidding suits you haven't got in auctions (or redoubling with no values) where it's a well known tactic usually doesn't. This is one of the best known auctions for responder's psyche and 99% of decent players know how to deal with it.
[I'm not complaining too much about this hand, as our team were EW at tables 2 & 4 so we gained imps overall. But it's the principle of the thing.]
